About this product

ZWO Full Frame 0.7x Focal Reducer for FF107 and FF130 Telescopes

ZWO has released this new 3-inch 0.7x full-frame reducer compatible with the FF107APO and FF130APO telescopes.

It has a three-element optical design, including one element made of ED glass.

Its reduction factor is 0.7, which gives the FF107APO a shortened focal ratio of f/4.9 and a shorter focal length of 524mm. This allows for less total integration time and a wider field of view, bringing more convenience and possibilities for your wide-field deep-sky imaging.

The FF130 is reduced to a focal length of 682mm and a focal ratio of f/5.25

The reducer has a standard 55mm back focus and comes with M68, M54, and M48 threaded adapters for easy attachment.

Connection steps:

1. Prepare the FF107/130APO telescope tube and the focal reducer.
2. Unscrew the M86 to 2-inch adapter at the end of the FF107/130APO telescope tube.
3. Unscrew the end cap of the 0.7X reducer.
4. Insert the reducer into the focuser inner tube and tighten it.
